Increasing need for studies of leaching water and possible pollutants through soil profiles led to the development of a method for placing large undisturbed soil monoliths in metal boxes for use as drainage lysimeters. Materials and equipment used in the technique are usually available or can be leased from local contractors. Monoliths as large as 1.5 m deep and with surface areas of 3 m have been taken. The technique could be used for even larger monoliths. Thus far, lysimeters have been installed in clay, sandy clay, loam and sand soils. The upper lip of several of the lysimeters described here was buried 25 cm below the surface to allow normal tillage, bed preparation and furrow irrigation.
